BALL-cock.

Specification of Letters Patent.

Application ledApril 14, 1919. Serial No. 289,974,

To all/whom it may concern:

Be it known that I, ALLEN R. j.(Srrniuonn, a citizen of the UnitedStates of America, a resident of the city of St. Louis, in the State ofMissouri, have invented certain new and useful Improvements in Ball-Cocks, of

which the following is a full, clear, and eX- `act description,reference lbeing had to the accompanying drawings, forming a partof thisspecification.

My` invention relates to a ball cockfor use.

I plunger, and sediment carried therewith,

may escape into the sediment chamber instead of traversing the length ofthe plunger and leaking through the end of the plunger chamber; toprovide further for the accurate seating of the plunger valve against atubular seat member against high water pressure, and in a manner whichwill eliminate vibration of the valve plunger.

Figure I is a vertical section through my ball cock.

Fig. II is an end elevation.

In the drawings, A designates a water-inlet pipe, and B a waterdischarge pipe leading respectively to and from my ball cock.

The ball cock housing C comprises a tubular inlet neck l connected tothe inlet pipe, a tubular discharge neck 2 to which the discharge pipe Bis connected, and a valve plunger chamber 3 communicableA with a waterreceiving chamber 4 adapted to communicate with the water inlet pipe Athrough the medium of a tubular valve seat member 5 interposed betweenthe housing neck l and the chamber 4.

The valve plunger chamber 3 extends through the end of the housing Copposite to that at which the valve seat member 5 is located, andimmediately beneath-the valve plunger chamber 3 is a sediment chamber 6,formed in the housing C and `having communication with the chamber 3through the medium of orifices 7 lea-ding from the valve plunger chamberto the sediment chamber. The. sediment Chamber is also placed incommunication with the interior of the discharge neck 2 by an orifice`8.

9 designates a valve plunger slidably arranged in the valve plungerchamber 3, said plunger extending to the outer end of the chamber 3 andterminating in a yoke 10 which pro-jects beyond the outer end of theplunger proper. The valve plunger 9 eX- tends across the water receivingchamber -i in the housing C, and is provided at its inner end with avalve 11 movable to and` from the tubular valve seat member 5 with whichthe valve is adapted to contact to prevent ilow of water from the inletpipe A to the chamber 4. It is important that the valve 11 should seataccurately and positively against the end'of the tubular valve seatmember with which it is to contact against high water pressure and it isalso desirable to prevent vibration and chatter of the valve plunger. Itherefore secure -to the inner end of the valve plunger a taperingnosepiece l2 serving to center the plunger in the tubular valve seatupon each movement of the valve to the valve seat member and hold thevalve from vibration.

The valve plunger 9 is provided with annular grooves 9 adapted toregister with the orifices 7 leading to the sediment chamber 6. Thesegrooves move into registration with said orifices 6 each time that thevalve plunger is retracted to open the valve, and any water passing fromthe water receiving chamber L along the valve plunger lenters theannular grooves therein and finds escape to the sediment chamber throughthe ports 7 Consequently, if there is any sediment or abrasive substancein the water which finds entrance to the valve plunger chamber 3, suchsubstance is quickly discharged into the sediment chamber, instead ofremaining in the valve plunger chamber to injure the plunger byabrasion. The annular grooves in the plunger 9 are also of service inthat they permit the formation of water packing around the plunger, withthe result of preventing the leakage of water through the outer open,end of the valve plunger' chamber, the water on reaching said annulargrooves forming liquid packing rings which are broken only by thepassage 'of the water to the sediment chamber 6 instead of through theopen end of the plunger chamber. Furthermore, by draining the water fromthe grooves in the valve Patented Cot. 28, i919..

plunger into the sediment. chamber, I obviate the presence of Wateraround the valve plunger when the valve is closed, thereby eliminatingcorrosion of the valve plunger which would result from the Waterremaining in contact with the plunger,

At the end of the valve housing C to which the valve plunger 9 extends,is an upper bracket arm 13 and a lower arm 14, the latter being providedwith a guide pin 15. The bracket arm 13 serves 'to support a lift arm 16pivoted to the bracketarm at 17, and to which a float rod 21 is secured.The lift arm 16 is provided With a roller 17.

ldesignates a valve plunger operating lever extending loosely throughthe yoke 'carried -by the valve plunger 9, the lower end of said leverbeing provided With an upwardly extending slot 19 occupied by the guideJpin 15. The plunger operating lever 18 is provided at its upper end withan open socket 20. This socket receives the roller 17 carried by thelift arm 16 to which ythe float rod 21 is attached.

The herein described plunger operating lever 18 and parts with which itis coperable are all so constructed as to permit quick removal andreplacement of said lever whenever it is necessary to repair the ballcock in any particular, as, lfor example, the renewing of the valvecarried by the valve plunger. This is true for the reason that theplunger operating lever has merely slip connection with the parts itengages and may be llid into and out of engagement there- Wit I claim:

1. A ball cock comprising-a housing having a Wate11eceiving chamber, aplunger chamber communicating with said Waterreceiving chamber, and a'sediment chamber in communication with said plunger chamber; and a valveplunger operable in said plunger chamber.

2. A ball cock comprising a housing having a water-receiving chamber, aplunger chamber communicating with said Waterreceivingchamber, and asediment chamber in communication with said plunger chamber; and a valveplunger operable in said plunger chamber, said plunger being providedwith a groove adapted to register with a point of communication betweensaid -plunger chamber and said sediment chamber.

3. A ball cock comprising a housing containing a Water-receivingchamber, a plunger chamber communicating With said water-receivingchamber, and a sediment chamber in communication with sai/d plungerchamber and having communication with the outlet from saidWater-receiving chamber; and a valve plunger operable in said plungerchamber, said plunger being grooved annularly to provide for theformation of a Water ring around the plunger from 'which Water enteringthe plunger chamber may pass to said sediment chamber.

In testimony that I claim the foregoing I hereunto aiiix my signature.
